2008 to 2014 Subaru Impreza WRX STi Gains Estimated 17 HP with K&N Air Intake
- May 3, 2010
K&N has developed an air intake system, part number 69-8005TWR for the 2008 to 2014 Subaru Impreza WRX STi with a 2.5 liter engine. K&N dynamometer testing shows an amazing 17.52 horsepower gain at 5260 rpm. The 69-8005TWR features an aluminum intake tube with a powder coated wrinkle red finish and a K&N carbon fiber top cone shaped universal air filter, part number RP-5113. The K&N washable and reusable air filter is isolated by a heat shield to help direct fresh outside air to the engine. The filter captures harmful particles, provides low restriction and also increases filter service life compared to the OEM air filter.
The impressive horsepower gain is also aided by the radius adaptor’s design as it smoothly takes the 5 inch flange of the air filter and connects it with the intake tube. The high-flow technology invented by K&N provides a great balance of airflow and filtration. Designed to be installed with simple hand tools in 90 minutes or less, this K&N air intake system is backed by the K&N Million Mile Limited Warranty.
